AUGUST O. JORDAN, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF OF HIS RIGHT TO JOHN ROBSON 8t SON.

COAL-WASHING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 231,429, dated August 24, 1880,

' Application filed May 15,1880. (No model.)

To all whom it may concern: the purpose of discharging into the chamber Be it known that I, AUGUST G. JORDAN, of the slate and pyrites which collect in the bot- Pittsburg, in the county of Allegheny and tom of the washing-chamber a.

It has a chamber, (1, on each side, and in drawings, making part of this specification, in each chamber (1 there is one or more vibrating 10 whichdoors or flaps, 6, provided with valves 0, and

between the grim]ingsurface oi' the feed-wheel 0 and thejaw p which is too hard to be broken thereby, and thus prevent a fracture of any of the parts of the machine. At the other end of the washingtank u is an elevator, r, having buckets 1', which turn around a pulley, 1' and take their load below the level of the overflow-opening n.

In the bottom of chamber 11 is an opening or openings, a, closed by a valve, 8, operated by a shaft and pinion, x from the outside, to discharge from the chamber the tine ret'use that passes through the screen I1.

Holes 1 are made in the valve-chamber (1, to permit the debris that falls into them to pass to the discharge a.

The operation of my improved washer is as follows: The coal is fed to the feeding-roll through the hopper m, which feed-roll, operating in connection with the jaw p, crushes and breaks up the material in the water and subjects it to action of the water. In this way it is more thoroughly cleansed by the water than it would be it erusliettiirst and then thrown in in bulk. The oscillation ot'the doors 0 makes a regularpulsation in the water, which causes the material in the tank to arrange itselfin layers according to the specitie gravity of the different parts, while the sudden and swift upward movement breaks up the banking ot' the coal, and the slower return causes it to settle gradually, which is further aided and accomplished bythe fact that the valves 4-, being held uptosomeextentbytheintlowingot'thestreams of water from the pipes close still more slowly. The water entering through pipes y, tlowing up through the loosened and descending mass in the washing-chamber a, on its way to the outlet a,loosensthe coal and lighter ret'use from the heavier debris and carries it up to the top, there depositing the coal and carrying the lighter refuse over the discharge.

The raising of the coal from out the washing-tank, instead of first washing it over into a settling-tank, enables me to save a quantity which otherwise would be lost, and consequently it is a more economical construction, saving both in construction and use.

The feeding-roll and crushing-jaw give a regular uniform feed of properly-sized material and prevent clogging.

This machine is very rapid in its operation and cleanses the coal thoroughly.

Instead ofhaving two chambers, 41, one may be used, which may be provided with but one oscillating wing, e.

I am aware that in ore-washers wherein the ore and water supply are fed to the machine above the screen, and the impulse given to the tank-water by a piston or plunger, a downwardly-opening valve has been provided on the plunger in order to prevent suction on the back-stroke, and do not claim the same, as it will be at once apparent that such a valve could not be of service in a machine wherein a continuous upward current of water was one of the agencies employed, as in my machine, and wherein the valve must open away from the inflowing current of Water.

hat I claim as my invention, and desire to secure by Letters Patent, is-- I. In a coal-washing machine, a serrated feed-roll combined with a crushing-jaw, said parts being placed in the washing-chamber below the level of the discharge-orifice, substantially as and for the purposes described.

2. In a coal-washing machine, the combination, with a water-tank having side chambers and oscillating or vibrating doors or flaps, of a doubleinclined screen and a central slate and refuse discharge, substantially as and for the purpose specified.

3. The combination, with the water-tank of a coal-washing machine, of a perforated bed or screen, a vibrating door or flap hung in the tank below the screen, said vibrating door or llap being provided with a valve, and a water induction or supply pipe or pipes located back of the vibrating valved door or flap, substantially as and for the purpose specified.

t. In a coal-washing machine, the combination, with the shaft of the oscillatingor vibrating door or flap, oi the cranks having slotted ends, which ends are connected to the wrist-pin of a driving-rod common to both cranks, a driving-rod common to both cranks and which is connected to and operated from an eccentric gear wheel, an eccentric gearwheel for actuating the driving-rod, anda second eccentric gear-wheel forimparting motion to the eccentric gear-wheel which actuates the driving-rod, substantially as and for the purpose spccitied.

5. The combination of the washing-tank and an elevator operating therein, which takes its load below the level of the discharge-orifice, substantially as and for the purposes described.

In testimony whereof I, the said AUGUST 0. JORDAN, have hereunto set my hand.

AUGUST G. JORDAN.
